Abstract

Abstract

A novel cement,magnesium phosphosilicate cement(MPSC) was studied.The main components of the cement are dead burned magnesia,phosphate and fly ash,and the content of fly ash in the dry binder is 40% by weight.MPSC has high early strength,which is very suitable for the rapid repair of deteriorated concrete structure.The bonding strength between MPSC and Portland cement concrete develops quickly.It also develops high early strength under the temperature below zero.Due to the small water to binder ratio and the special microstructure,MPSC possesses of higher resistantce to freezing-thawing cycle scaling.
- magnesium phosphate cement,
- fly ash,
- early strength,
- freezing-thawing,
- cycle scaling
